Processes for treating morphologically-modified silicon electrode surfaces using gas-phase interhalogens
Processes for treating a morphologically-modified surface of a silicon upper electrode of a plasma processing chamber include exposing the surface to a gas composition containing at least one gas-phase halogen fluoride. The gas composition is effective to remove silicon from the morphologically-modi...

| Zusammenfassung: | Processes for treating a morphologically-modified surface of a silicon upper electrode of a plasma processing chamber include exposing the surface to a gas composition containing at least one gas-phase halogen fluoride. The gas composition is effective to remove silicon from the morphologically-modified surface and restore the surface state. |
